Until recently, companies that beat quarterly earnings estimates could routinely expect their shares to rise, sometimes dramatically. Not anymore. This year so far, many earnings overachievers have seen small price gains, or even declines. It’s unclear why. One theory is that buyers’ fatigue is setting in more than eight years into the second-longest bull market in U.S. history. Another is simply that the low-expectations game, whereby companies and analysts have for years crafted easy-to-beat forecasts for earnings and revenues, then surpassed them with great fanfare—but not always much surprise—is losing its punch.
 
Whatever the reason, investors should watch how shares respond to quarterly reports as closely as they watch the financial results themselves. Research suggests the combination of better-than-predicted earnings and revenue, followed by a quick, positive price reaction, tends to predict market-beating performance for months to come. Although there’s a shortage of such true upside surprisers, we’ve found some, including Caterpillar (ticker: CAT) and Analog Devices (ADI).
 
Whether or not earnings surprises have been genuine, growth appears healthy. Earnings per share grew 10% in the latest quarter over a year ago, helped by the energy sector’s rebound from a low base. Although that’s a bit below the first quarter’s growth rate, the trend confirms a return to reasonable profit expansion following a two-year stall. That is important if companies are to grow into their share prices, never mind enjoy further stock-price gains. The Standard & Poor’s 500 index recently traded at 20 times the past four quarters’ earnings, versus a historical average of closer to 15 times.
 
Even more encouraging has been the improvement in earnings quality. The divide between the earnings companies are legally required to report, warts and all, and the prettied-up version they prefer to highlight is gently shrinking, suggesting there is less excuse-making and more genuine growth.


So where’s the applause? Nearly three-quarters of companies beat earnings estimates in their latest quarterly reports. While the S&P 500 is up a toast-worthy 11% on the year, fewer than half its components have seen any price increase on the trading day following their latest quarterly report, and fewer than a third have recorded a gain of 1% or more. Overall, investors have grown less impressed with upside surprises, even though their number is as high as ever.
 
 
Researchers documented as far back as 1968 that companies beating earnings estimates tend to outperform the market for months afterward, a phenomenon called post-earnings-announcement drift, or PEAD. As companies have gotten better at guiding toward beatable numbers, and as analysts have gotten better at playing along, the magnitude of PEAD seems to have diminished. But there are several ways to bolster it.
 
 



One is to look for companies that surprise to the upside on revenue as well as earnings. Past research by Joshua Livnat of New York University and Narasimhan Jegadeesh of Emory University has shown that companies surpassing both revenue and earnings estimates tend to outperform the market over time by more than companies beating on earnings alone. Perhaps that’s because revenue is more difficult to massage.
 
Another way to sort for real, as opposed to engineered, earnings surprises is suggested by a study published in 2012 in the Financial Analysts Journal. It found that a strategy of buying stocks with upside earnings surprises and quick share-price jumps, and shorting the reverse, tended to return a handsome 15% a year.
 
GUIDED BY THESE STUDIES, Barron’s recently screened for S&P 500 companies that topped both earnings and revenue estimates by at least 1% in each of the past three quarters, and experienced a one-day price increase of at least 1% after reporting results. Some 194 companies qualified on earnings beats alone, and 48 did so on both earnings and revenue beats. But a mere three—Analog Devices, Delphi Automotive (DLPH), and Agilent Technologies (A)—made the cut on all criteria.
 
To expand the list with a focus on more recent momentum, we then screened for companies that surpassed earnings and revenue estimates by at least 3% in the most recent quarter and saw a price jump of at least 5% in response.

Stock screens reduce a vast universe of choices to a manageable few for further consideration, but they don’t quite spit out a Buy list. Our screen turned up 13 names; we chose five that look particularly promising based on growth opportunities. This list includes Caterpillar, Analog, Align Technology (ALGN), E*Trade Financial (ETFC), and Red Hat (RHT), a seller of open-source software solutions.
 
ALIGN TECHNOLOGY has tripled in price in the past two years, outrunning Facebook (FB), Amazon.com (AMZN), and Netflix (NFLX). Align is in the crooked-teeth business, not the dot-com business, except to the extent that its digital services are accelerating demand for its Invisalign orthodontic trays. A new system doesn’t require goop and dental-mold setting, just a three-dimensional mouth scan, with measurements zipped to the factory. Treatment is faster than braces.
 
Wall Street found plenty to like in Align’s latest quarterly report, including a surge in North American treatments, especially among teens. That’s important, because teens make up an estimated 75% of the teeth-straightening market, and Align has only a 5% share so far. The shares, at $185, fetch 48 times forward earnings estimates, but earnings could double in three to four years, as those digital tools continue to lure more Invisalign patients.
 
CHIP MAKER Analog Devices makes some innards for Apple’s (AAPL) iPhone and other gadgets, but two-thirds of its business is tied to industrial and automotive applications. There, silicon is proliferating to enable smart everything, from factory machines that can tell when they’re ready for maintenance, to cars that brake automatically. The dollar amount of semiconductor content in cars is expected to triple in a decade.
 
Barron’s recommended Analog Devices stock in May. It has returned 6% since then, a smidgen more than the market, and still looks inexpensive at a recent $82.34, or 17 times forward earnings estimates. In the latest quarter, investors liked that results from Analog’s car segment were better than expected, even as vehicle sales have slipped.
 
CATERPILLAR IS ENJOYING a sudden sales- growth spurt after a four-year slump. Barron’s turned bullish on the stock two years ago at $77, and doubled down in an April 2017 cover story with the shares at $102. The stock was recently at $120, or 18 times next year’s projected earnings of $6.56 a share.
 
A week ago, management, including new CEO Jim Umpleby, held Caterpillar’s first investor day in three years. He laid out a long-term plan to get to $55 billion in yearly revenue, with 14% to 17% operating profit margins. This year’s forecast puts revenue at $43 billion and margins at 10.9%.
 
BMO Capital Markets analyst Joel Tiss calculates that Cat’s new targets imply $9 to $11 in earnings per share. In the latest quarter, the company not only trounced estimates and raised its full-year forecasts, but said its backlog of new business swelled 25% from a year ago.
 
E*TRADE FINANCIAL is benefiting from a surging stock market, which is boosting assets, trading volume, and margin balances. The company has topped Wall Street’s earnings estimates by more than 20%, on average, for the past eight quarters. Yet the stock recently traded at a 22% discount to Charles Schwab (SCHW) and a 24% discount to TD Ameritrade Holding (AMTD), based on forward earnings estimates.  

E*Trade’s market value is half that of Ameritrade and less than a quarter of Schwab’s. That suggests the company could become a takeover target, especially because the online brokerage industry is crowded, putting pressure on fees. Deutsche Bank analyst Brian Bedell estimates E*Trade could be bought out at anywhere from 8% to 40% above its recent stock price of $40.72.
 
RED HAT HAS RETURNED 47% since Barron’s recommended the stock in May 2016. The company’s core business is selling access to Linux, an open-source computer operating system available to casual users for free. Red Hat Enterprise Linux is a carefully curated, serviced, and secured version of the software favored by banks, hospitals, and other businesses for which reliability is key. The company also makes Red Hat OpenStack, for moving local computer networks into the cloud, and Red Hat OpenShift, which helps programmers write software to run in a variety of settings, including cloud platforms from Amazon and Microsoft (MSFT).
 
Red Hat posted upside surprises and raised its guidance in the quarter just passed, and investors might have been particularly cheered by results in newer business lines. Although the company doesn’t break out OpenShift revenue, analysts say it has been more than doubling year on year from a low base. At $108, shares sell for 37 times forward earnings estimates, but a less-expensive 22 times free cash flow.
